He doesn't exactly need a permit to live alone (6)
I believe the answer is:
hermit
'he doesn't exactly need a permit to live alone' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot really see how this works, but
'he' is within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for hermit that I've seen before include "Kind of crab that lives in a cast-off shell" , "Solitary person, anchorite" , "Eremite" , "Person or crab living in solitude" , "Solitary religious" .)
